If you were to use the physical distance in terms of size as a model, the height a fly can in one jump will for man work out as high as the Empire State building. This is only a hypothetical model. The different flavors quarks come up with, do indicate space in such infinitesimal confines: correspondence principle gives space a yardstick on which infinite or the least can be held up.
At the level of quarks is there time or space? We might tag so many flavors make up proton or neutron just as we would lay a sheet in vast expanse of grass to have a picnic and call it as our space. Once picnic is over and sheet is taken out, folded and we drive away the so called space is dissolved. So is time. These are only related to us. Yet its reality as a memory(of a picnic on Sunday for example) is swallowed up in space where in we create our realities of everyday life in space. It is only relevant to the observer like finding parking space for your car.
Time is similarly related to the observer.
If God is to conceived as eternal, infinite and omnipresent He must hold as real to me as in the cosmos. As a Christian I believe essence of God is achieved in space regardless of such an infinitesimal space. ‘The kingdom of God is within you.’ Gluons are stronger nuclear force binding realities of sub-atomic particles ie quarks. What makes us believe in physical reality of our bodies and ideas? Do we not believe in our world or in our bodies? Just the same these come up as ever with otherworldly tags.
Our faith though as small as mustard seed can grow as large as to cover as the will of God covers the entire cosmos. God has inscribed truth in our inward parts.
